In October 2025 I travelled to El Hierro, the smallest of the Canary Islands, to test one question: is the island a replicable laboratory of sustainability, or an experiment sustained by conditions no other place can copy? This section gathers everything that came out of that reporting trip: a long-form report, a photo essay, a short film and a podcast, a travel guide and a logbook written before, during and after the trip.
My provisional answer: El Hierro works as a laboratory when it manages limits; it turns into an experiment when success pushes it to ignore them.
